So, to adapt to Sony, what is the less bad Leica-M mount lens? Which one of the slow ones?
The better performance on the Sony camera is achieved with slower lenses in the 28mm category. Notable choices within this range include the Leica 28/5.6 Summaron, the discontinued Voigtlander 28/3.5, and the new Voigtlander 28/2.8.
It's crucial to take into account that when adapting these lenses to the Sony system, there might be a decrease in corner performance when focusing on the center, especially if the corners fall within the same focus plane. Stopping down the lens aperture, will increase depth of field. This, in turn, helps to mask the pronounced field curvature that arises from the thicker sensor stack.
When shooting wide open, the subject in focus will show great sharpness across the field. However, there will be a magnified and undesirable field curvature effect in the rendering. For example, when focusing on a subject at the center and mid-distance, it might cause distant corner areas to appear sharper due to the induced field curvature shape, rather than being out of focus.
